▎ 摘　　要

NOVELTY - A graphene-oxide-modified anti-wear agent is prepared by adding graphene oxide and compound containing boron, calcium copper, and rare earth elements in three-neck flask, stirring in organic solvent while heating, adding concentrated sulfuric acid as catalyst, increasing temperature to boiling point of solvent, and vacuum-drying the product. USE - Preparation of graphene-oxide-modified anti-wear agent (claimed). ADVANTAGE - Graphene oxide is ultra-thin, hard, super lubricating, and corrosion resistant and has high temperature characteristics, resulting in anti-wear agent with improved lubricating property, which greatly reduces friction and abrasion of machinery motion surface, and material-saving and energy- saving effects.
